IME, its going to be impossible to tell if its 660 through pics. You will have to rely on the manufacturer or see a 660 from another hobbyist's tank. As long as its red, I think you your ATS will be fine.

iv seen others having pink.... but i guess thats due to the combitation of blue with red...... isnt it that?

[Terrance]

Yes; even a 6:1 red blue ratio makes pink.
